Description

車両用シートVehicle seat
本発明は、チャイルドシートを保持可能とするアンカを有した車両用シートに関する。 The present invention relates to a vehicle seat having an anchor that can hold a child seat.
車両用シートに対するチャイルドシートの保持方式として、たとえば国際標準規格ＩＳＯ－ＦＩＸがあり、このＩＳＯ－ＦＩＸタイプのチャイルドシートを保持可能とするＩＳＯ－ＦＩＸ対応のアンカを有した車両用シートが、たとえば特開２００２－２１１２８７号公報等において開示されている。　 As a method for holding a child seat with respect to a vehicle seat, for example, there is an international standard ISO-FIX. A vehicle seat having an ISO-FIX compatible anchor capable of holding a child seat of this ISO-FIX type is disclosed in, for example, No.-211287 and the like. *
この種のＩＳＯ－ＦＩＸタイプのチャイルドシートにおいては、その後部に左右一対の係合部材が設けられ、この係合部材を受けるアンカが、車両用シートのシートクッションの後端等に配設される。　 In this type of ISO-FIX child seat, a pair of left and right engaging members are provided at the rear thereof, and an anchor that receives the engaging members is disposed at the rear end of the seat cushion of the vehicle seat. *
アンカとして、前方に互いに平行に延びた左右一対のサイドバーの前端をフロントバーで連結した平面視略コ字形状にワイヤ材(中実棒材)を折曲加工して成形されたものが知られている。チャイルドシートは後方へ延びた左右一対の係合部材を背面下部に持ち、係合部材は長溝状の切欠き(係合口)を先端に持つ側面視略二股形状に形成され、係合部材先端の係合口をアンカのフロントバーに係合させることによってチャイルドシートがアンカに保持される。通常、係合部材の下の腕は、係合部材がフロントバーと円滑に係合するように、上の腕よりも短く形成される。　 As an anchor, a wire material (solid bar material) is formed by bending a wire material (solid bar material) into a substantially U-shape in plan view where the front ends of a pair of left and right side bars extending in parallel to each other in front are connected by a front bar. It has been. The child seat has a pair of left and right engaging members extending rearward at the lower part of the back, and the engaging members are formed in a substantially bifurcated shape in side view with a long groove-like notch (engagement port) at the tip. The child seat is held by the anchor by engaging the joint with the front bar of the anchor. Usually, the lower arm of the engaging member is formed shorter than the upper arm so that the engaging member smoothly engages with the front bar. *
アンカはシートクッション後端またはシートバック下端に設けられる。シートクッション、シートバックは、いずれも、その骨格となるシートクッションフレームに発泡ウレタン等の発泡材からなるパッドを被せ、パッドをトリムカバーで被覆して構成されている。アンカをシートクッション後端に設ける場合について述べると、シートクッションフレームは、左右のサイドフレームの前後端を、たとえば連結パイプで連結した平面視略矩形形状に成形され、アンカは、前後の連結パイプのうちの後方の連結パイプに固定されて、シートクッション後端に設けられる。　 The anchor is provided at the rear end of the seat cushion or the lower end of the seat back. Each of the seat cushion and the seat back is configured by covering a seat cushion frame serving as a skeleton with a pad made of a foamed material such as urethane foam and covering the pad with a trim cover. The case where the anchor is provided at the rear end of the seat cushion will be described. The seat cushion frame is formed into a substantially rectangular shape in a plan view in which the front and rear ends of the left and right side frames are connected by, for example, a connecting pipe. It is fixed to the connecting pipe at the back of the seat and provided at the rear end of the seat cushion. *
シートクッション後端にアンカを配置するために、アンカを収納する凹部がパッドに形成され、凹部の上でトリムカバーは開口され、開口を囲むトリムカバーの端末が処理(端末処理)される。　 In order to arrange the anchor at the rear end of the seat cushion, a recess for accommodating the anchor is formed in the pad, the trim cover is opened on the recess, and the end of the trim cover surrounding the opening is processed (terminal processing). *
特開２００２－２１１２８７号公報では、アンカのサイドバーの後端を連結パイプの上面から後周面に沿って巻き付け、巻き付けたサイドバーの後端をブラケットで後方から前面を覆ってサイドバーの後端及びブラケットを連結パイプに溶接して固定する構成が記載されており、ブラケットでアンカを覆って補強している。 In Japanese Patent Application Laid-Open No. 2002-2111287, the rear end of the side bar of the anchor is wound from the upper surface of the connecting pipe along the rear peripheral surface, and the rear end of the wound side bar is covered with the bracket from the rear to cover the front of the side bar. The structure which welds and fixes an end and a bracket to a connecting pipe is described, and the anchor is covered and reinforced.
特開２００２－２１１２８７号公報JP 2002-211287 A
通常、チャイルドシートは、背面側が沈んだ傾斜した姿勢で、背面の係合部材をシートクッション後端のアンカのフロントバーに係合されるが、チャイルドシートが傾斜しているため、略二股形状の係合部材が開口後方のトリムカバー端末を噛むおそれがある。特に、係合部材の下の腕が上の腕よりも短く形成されていると、下の腕がトリムカバー端末を噛みやすい。　 Normally, the child seat is in a tilted position with the back side sinking, and the engagement member on the back side is engaged with the front bar of the anchor at the rear end of the seat cushion. The member may bite the trim cover terminal at the rear of the opening. In particular, when the lower arm of the engaging member is formed shorter than the upper arm, the lower arm can easily bite the trim cover terminal. *
係合部材の下の腕がトリムカバーの開口に入り込んで開口後方のトリムカバー端末を噛むと、係合部材先端の係合口にトリムカバー端末が噛み込まれ、フロントバーが係合部材の係合口の末端に至らず係合不良となって、アンカによるチャイルドシートの保持が不完全なものとなるおそれがある。



　また、係合部材が開口後方のトリムカバー端末を噛んで係合口への噛み込みが生じると、係合口に噛み込まれたトリムカバー端末が損傷して、トリムカバーの外観品質が損なわれる。　 When the lower arm of the engagement member enters the opening of the trim cover and bites the trim cover terminal at the rear of the opening, the trim cover terminal is engaged with the engagement port at the front end of the engagement member, and the front bar is the engagement port of the engagement member. There is a risk that the child seat will be incompletely held by the anchor due to poor engagement without reaching the end.



Further, when the engagement member bites the trim cover terminal at the rear of the opening and biting into the engagement port occurs, the trim cover terminal bited into the engagement port is damaged, and the appearance quality of the trim cover is impaired.
特開２００２－２１１２８７号公報のようにアンカの取付けのためにブラケットを用いると、アンカを収納するパッドの凹部が前後方向で長くなって、係合部材先端の係合口へのトリムカバー端末の噛み込みが生じやすくなる。


When a bracket is used to mount an anchor as in Japanese Patent Application Laid-Open No. 2002-211287, the recess of the pad for housing the anchor becomes longer in the front-rear direction, and the trim cover terminal bites into the engagement port at the front end of the engagement member. It tends to occur.


本発明は、ブラケットを用いても係合部材先端の係合口へのトリムカバー端末の噛み込みを防止できる車両用シートの提供を目的としている。 An object of the present invention is to provide a vehicle seat that can prevent the trim cover terminal from being caught in the engagement port at the distal end of the engagement member even if a bracket is used.
本発明では、連結部材がブラケットとトリムカバーの開口の後方のトリムカバー端末との間に張設されて、開口後方のトリムカバーの端末をパッドの凹部に引き込んでいる。



　すなわち、請求項１に係る本発明によれば、車両用シートはチャイルドシートの保持に使用されるアンカを有し、アンカは、左右一対のサイドバーの前端をフロントバーで連結した平面視略コ字形状に形成されて、フロントバーにチャイルドシート背面の係合部材が係合可能とされ、サイドバーは、左右方向に架設されたシートクッションまたはシートバックの連結パイプにブラケットを介して固定され、アンカを収納する凹部がシートクッション後端、シートバック下端のいずれかでパッドに形成され、パッドを覆うトリムカバーがパッドの凹部の上で開口され、チャイルドシート背面の係合部材は、アンカのフロントバーが係合可能な係合口を先端に持つ側面視略二股形状とされ、トリムカバーの開口を囲むトリムカバーの端末のうち、開口後方のトリムカバーの端末に一端が連結され、他端がブラケットに係止された連結部材が、連結パイプを巻装して開口後方のトリムカバー端末とブラケットとの間に張設されて、開口後方のトリムカバーの端末をパッドの凹部に引き込んでいる。 In the present invention, the connecting member is stretched between the bracket and the trim cover terminal behind the opening of the trim cover, and the terminal of the trim cover behind the opening is drawn into the recess of the pad.



That is, according to the first aspect of the present invention, the vehicle seat has an anchor used for holding the child seat, and the anchor is substantially U-shaped in plan view in which the front ends of the pair of left and right side bars are connected by the front bar. It is formed in a shape, and the engaging member on the back of the child seat can be engaged with the front bar, and the side bar is fixed to the seat cushion or the seat back connecting pipe laid in the left and right direction via the bracket, and the anchor is The recessed part to be stored is formed in the pad at either the rear end of the seat cushion or the lower end of the seat back, the trim cover that covers the pad is opened above the recessed part of the pad, and the engaging member on the back of the child seat is engaged with the front bar of the anchor. Of the trim cover terminal surrounding the opening of the trim cover, the engagement opening at the tip has a substantially bifurcated shape. A connecting member having one end connected to the end of the trim cover at the rear of the mouth and the other end locked to the bracket is wound between the trim cover terminal at the rear of the opening and the bracket by winding the connecting pipe, The end of the trim cover at the rear of the opening is drawn into the recess of the pad.
請求項１に係る本発明では、連結部材が、連結パイプを巻装して開口後方のトリムカバー端末とブラケットとの間に張設されて、開口後方のトリムカバーの端末をパッドの凹部に引き込むことによって、開口後方のトリムカバーの端末が下方に逃がされる。そのため、チャイルドシートの背面側が沈んだ傾斜した姿勢で、背面の係合部材をアンカのフロントバーに係合させても、係合部材が開口後方のトリムカバー端末を噛むことがなく、係合部材先端の係合口へのトリムカバー端末の噛み込みが防止される。 In the present invention according to claim 1, the connecting member is wound between the trim cover terminal and the bracket at the rear of the opening by winding the connecting pipe, and the terminal of the trim cover at the rear of the opening is drawn into the recess of the pad. As a result, the end of the trim cover behind the opening is released downward. Therefore, even if the engagement member on the back is engaged with the front bar of the anchor in the inclined posture in which the rear side of the child seat is sunk, the engagement member does not bite the trim cover terminal at the rear of the opening, and the front end of the engagement member The trim cover terminal is prevented from biting into the engagement port.

The anchor front bar 30b is engaged until it reaches the end of the engagement port 24a of the engagement member, whereby the child seat 20 is completely held by the anchor 30 (see FIG. 3A). *
図４はブラケットを介在してアンカが固定された連結パイプとの直交面でのシートクッションの概略部分断面図を示す。図４に示すように、シートクッション後端でパッド１４－１を切り欠いて凹部１４－１’が形成され、パッドを覆うトリムカバー１４－２はパッドの凹部の上で開口され、開口１４－２’の回りのトリムカバーの端末(開口前方の端末１４－２ａ、開口後方の端末１４－２ｂなど)はたとえば縫合によって処理(端末処理)されている。実施例では、パッド凹部１４－１’は上下方向でパッドを貫通して形成されているが、底付形状としてもよい。　 FIG. 4 shows a schematic partial cross-sectional view of the seat cushion in a plane orthogonal to the connecting pipe to which the anchor is fixed via a bracket. As shown in FIG. 4, the pad 14-1 is cut out at the rear end of the seat cushion to form a recess 14-1 ′, and the trim cover 14-2 covering the pad is opened above the recess of the pad. The terminals of the trim cover around 2 ′ (terminal 14-2a at the front of the opening, terminal 14-2b at the rear of the opening, etc.) are processed (terminal processing) by, for example, sewing. In the embodiment, the pad recess 14-1 'is formed through the pad in the vertical direction, but may have a bottomed shape. *
図２、図３に示すように、アンカ３０は、サイドフレームの後端間で左右方向に架設された後方の連結パイプ１６に、直立位置から斜め前方に延出するようにブラケット３２を介して固定されて、パッド凹部１４－１’(図４参照)にブラケットとともに収納、配置されている。ブラケット３２は、左右一対のサイド壁３２ａの前端をフロント壁３２ｂで連結した平面視略コ字形状に、たとえば鋼板をプレス加工して成形され、ブラケットの内面にアンカの左右一対のサイドバー３０ａの後端が固定されている。サイドバー３０ａのブラケット３２の内面への固定は、たとえば溶接により行われるが、これに限定されない。　 As shown in FIG. 2 and FIG. 3, the anchor 30 is connected to the rear connection pipe 16 laid in the left-right direction between the rear ends of the side frames via the bracket 32 so as to extend obliquely forward from the upright position. It is fixed and accommodated and arranged with the bracket in the pad recess 14-1 ′ (see FIG. 4). The bracket 32 is formed, for example, by pressing a steel plate into a substantially U shape in plan view in which the front ends of the pair of left and right side walls 32a are connected by the front wall 32b. The rear end is fixed. Although fixation to the inner surface of the bracket 32 of the side bar 30a is performed by welding, for example, it is not limited to this. *
図２に示すように、サイドバー３０ａの後端は、サイド壁３２ａ、フロント壁３２ｂの角部でそれぞれの内面に固定しているが、これに限定されず、たとえばサイド壁から離反した位置でフロント壁の内面（背面）に固定してもよい。しかしながら、サイドバー３０ａの後端をサイド壁３２ａ、フロント壁３２ｂの角部に配置すれば、サイド壁、フロント壁の両方に溶接できるので強固に固定できる。　 As shown in FIG. 2, the rear ends of the side bars 30a are fixed to the inner surfaces at the corners of the side wall 32a and the front wall 32b. However, the present invention is not limited to this, for example, at a position away from the side wall. You may fix to the inner surface (back surface) of a front wall. However, if the rear end of the side bar 30a is disposed at the corners of the side wall 32a and the front wall 32b, it can be firmly fixed because it can be welded to both the side wall and the front wall. *
ブラケットのサイド壁３２ａの後端には、連結パイプ１６の前周面に対応した円弧形状の切欠き３２ｃが形成されている。アンカ３０の固定されたブラケット３２は、その切欠き３２ｃが連結パイプ１６の前周面を抱持するように、係合部材２４と対応する位置に前方から連結パイプに取り付けられる。このとき、サイドバー３０ａが直立位置から斜め前方に延出し、サイドバーが変形してサイドバーとともに係合部材２４が下降したとき、係合部材が当接する位置で、ブラケット３２は連結パイプ１６にたとえば溶接によって固定されている。　 At the rear end of the side wall 32a of the bracket, an arc-shaped notch 32c corresponding to the front peripheral surface of the connecting pipe 16 is formed. The bracket 32 to which the anchor 30 is fixed is attached to the connecting pipe from the front at a position corresponding to the engaging member 24 so that the notch 32c holds the front peripheral surface of the connecting pipe 16. At this time, when the side bar 30a extends obliquely forward from the upright position and the side bar is deformed and the engaging member 24 is lowered together with the side bar, the bracket 32 is attached to the connecting pipe 16 at a position where the engaging member abuts. For example, it is fixed by welding. *
図３（Ａ）に示すように、実施例ではアンカのサイドバー３０ａは直立位置より１５°前方へ傾斜して延出しているが、この前傾角αは１５°に限定されない。前傾角αは、サイドバー３０ａが主として曲げ変形でなく座屈変形を生じる角度であれば足り、たとえば、１０～２５°とされる。



　ブラケットのフロント壁の上端３２ｂ’が連結パイプ１６から最も離反した位置にあるから、通常、下降する係合部材の下面２４’がフロント壁の上端に当接するようにブラケット３２は位置決めされる。しかしながら、係合部材の下面２４’とブラケットのフロント壁上端３２ｂ’との当接に限定されず、下降する係合部材２４が当接してその下降を阻止する位置（係合部材の下方位置）にブラケットがあればよい。　 As shown in FIG. 3A, in the embodiment, the anchor side bar 30a is inclined and extended forward by 15 ° from the upright position, but the forward inclination angle α is not limited to 15 °. The forward inclination angle α need only be an angle at which the side bar 30a mainly undergoes buckling deformation instead of bending deformation, and is, for example, 10 to 25 °.



Since the upper end 32b 'of the front wall of the bracket is at the position farthest from the connecting pipe 16, the bracket 32 is usually positioned so that the lower surface 24' of the lowering engagement member abuts the upper end of the front wall. However, the position is not limited to the contact between the lower surface 24 ′ of the engagement member and the front wall upper end 32 b ′ of the bracket. There should be a bracket.
通常、チャイルドシート２０は、アンカ３０への係合部材２４の係合とともに、テザーベルトを利用してシート１０に保持されるが、テザーベルトは本発明と直接関係しないのでその説明は省略する。　 Normally, the child seat 20 is held on the seat 10 using the tether belt together with the engagement of the engaging member 24 to the anchor 30. However, the tether belt is not directly related to the present invention, and the description thereof is omitted. *
係合部材２４の先端に設けられる係合口（切欠き）２４ａは、実施例では長溝形状としているが、アンカ３０（フロントバー３０ｂ）と係合して、チャイルドシート２０をシートクッション１４に保持可能であれば足り、長溝形状に限定されない。



　なお、係合部材２４は係合口２４ａを有するため、上下に腕２４Ｕ、２４Ｌを持つ側面視略二股形状とされ、アンカのフロントバー３０ｂと円滑に係合するように、下の腕２４Ｌは上の腕２４Ｕよりも短く形成されている。　 The engagement port (notch) 24a provided at the distal end of the engagement member 24 has a long groove shape in the embodiment. However, the child seat 20 can be held on the seat cushion 14 by engaging with the anchor 30 (front bar 30b). It is sufficient as long as it is long, and it is not limited to the long groove shape.



Since the engagement member 24 has an engagement port 24a, the engagement member 24 has a substantially bifurcated shape in the side view with the arms 24U and 24L on the upper and lower sides, and the lower arm 24L is arranged to be smoothly engaged with the anchor front bar 30b. It is shorter than the arm 24U.
図４に示すように、帯状の連結部材４０が開口後方のトリムカバー端末１４－２ｂとブラケット３２との間に張設されて、開口後方のトリムカバーの端末をトリムカバーの開口１４－２’、つまりは、パッド凹部１４－１’に引き込んでいる。



　図５は連結部材の斜視図を示し、概略、初期形状は一点鎖線に示す平板形状とされ、使用時には実線で示す形状で取付けられる。　 As shown in FIG. 4, a strip-shaped connecting member 40 is stretched between the trim cover terminal 14-2b at the rear of the opening and the bracket 32, and the terminal of the trim cover at the rear of the opening is connected to the opening 14-2 ′ of the trim cover. That is, it is drawn into the pad recess 14-1 ′.



FIG. 5 is a perspective view of the connecting member. The outline and initial shape are flat plate shapes indicated by a one-dot chain line, and are attached in a shape indicated by a solid line when in use.
帯状の連結部材４０は伸縮性、引張強度を兼ね備えた布材から成形され、たとえば、トリムカバーと同じ布材でもよく、シートベルトのストラップと同じポリエステル繊維などの布材であれば申し分ない。



　連結部材の一端４０ａは開口後方のトリムカバー端末１４－２ｂに縫合されており、他端４０ｂは、連結パイプ１６に巻装して差し渡されて、ブラケット３２、詳細には、ブラケットのフロント壁３２ｂに係止されている。ここで、フック形状の係止片４２が連結部材の他端４０ｂに取付けられており、フロント壁の上端３２ｂ’に係止片を係止させることにより、連結部材の他端をブラケット３２にワンタッチで係止できる。そして、連結部材４０が、開口後方のトリムカバー端末１４－２ｂ、ブラケット３２の間で連結パイプ１６を巻装して張設され、トリムカバー端末１４－２ｂをパッドの凹部１４－１’に引き込んで下方に逃がすことができる。　 The belt-shaped connecting member 40 is formed from a cloth material having both stretchability and tensile strength. For example, it may be the same cloth material as that of the trim cover.



One end 40a of the connecting member is sewn to the trim cover terminal 14-2b at the rear of the opening, and the other end 40b is wound around the connecting pipe 16 and passed through the bracket 32, specifically, the front wall of the bracket. It is locked to 32b. Here, a hook-shaped locking piece 42 is attached to the other end 40b of the connecting member, and the other end of the connecting member is one-touched to the bracket 32 by locking the locking piece to the upper end 32b ′ of the front wall. It can be locked with. The connecting member 40 is stretched by winding the connecting pipe 16 between the trim cover terminal 14-2b at the rear of the opening and the bracket 32, and the trim cover terminal 14-2b is drawn into the recess 14-1 ′ of the pad. You can escape downward.
係止片４２は、たとえば、樹脂材から成形され、係止片を樹脂材から成形すれば布材からなる連結部材の他端４０ｂに縫合によって容易に取付けられる。



　係止片４２の露出を避けるために、実施例では、布片１４－３によって係止片が覆われて隠されている。たとえば、トリムカバー１４－２と同じ材質の布片１４－３の一端が、開口前方のトリムカバー端末１４－２ａに縫合され、他端が係止片４２を覆って凹部１４－１’に垂下させることによって係止片が隠される。　 The locking piece 42 is formed from, for example, a resin material. If the locking piece is formed from a resin material, the locking piece 42 is easily attached to the other end 40b of the connecting member made of a cloth material by stitching.



In order to avoid the exposure of the locking piece 42, in the embodiment, the locking piece is covered and hidden by the cloth piece 14-3. For example, one end of the cloth piece 14-3 made of the same material as that of the trim cover 14-2 is stitched to the trim cover terminal 14-2a in front of the opening, and the other end covers the locking piece 42 and hangs down into the recess 14-1 ′. By doing so, the locking piece is hidden.
図１に示すように、チャイルドシートの背面側が沈んだ傾斜した姿勢で、チャイルドシート背面の係合部材２４をシートクッション後端のアンカのフロントバー３０ｂに係合されるが、チャイルドシートが傾斜しているため、略二股形状の係合部材が開口後方のトリムカバー端末１４－２ｂを噛むおそれがある。　 As shown in FIG. 1, the child seat rear engagement member 24 is engaged with the anchor front bar 30b at the rear end of the seat cushion in a tilted posture in which the rear side of the child seat sinks, but the child seat is inclined. There is a possibility that the substantially bifurcated engagement member may bite the trim cover terminal 14-2b behind the opening. *
しかしながら、連結パイプ１６を巻装して開口後方のトリムカバー端末１４－２ｂとブラケット３２との間に連結部材４０を張設してトリムカバーの端末をパッド凹部１４－１’に引き込んで開口後方のトリムカバーの端末を下方に逃がしている。そのため、チャイルドシート２０の背面側が沈んだ傾斜した姿勢で、係合部材２４をアンカのフロントバー３０ｂに係合させても、係合部材の下の腕２４Ｌが開口後方のトリムカバー端末１４－２ｂを噛むことがなく、係合部材先端の係合口へのトリムカバー端末の噛み込みが防止される。



　そして、トリムカバー端末が係合部材の係合口２４ａに噛み込まれないため、アンカのフロントバー３０ｂが係合口の末端まで入り込んで係合され、チャイルドシート２０がアンカ３０に確実に保持される。



　また、トリムカバー端末が係合部材の係合口２４ａに噛み込まれないため、係合部材によるトリムカバー端末の損傷が避けられ、トリムカバーの外観品質が損なわれない。　 However, the connecting pipe 16 is wound around and the connecting member 40 is stretched between the trim cover terminal 14-2b and the bracket 32 at the rear of the opening, and the terminal of the trim cover is pulled into the pad recess 14-1 'so that the rear of the opening. The end of the trim cover is released downward. Therefore, even if the engagement member 24 is engaged with the anchor front bar 30b in the inclined posture in which the rear side of the child seat 20 is sinked, the arm 24L below the engagement member holds the trim cover terminal 14-2b behind the opening. The trim cover terminal is prevented from biting into the engagement port at the tip of the engagement member without being bitten.



Since the trim cover terminal is not caught in the engagement port 24a of the engagement member, the front bar 30b of the anchor enters and engages to the end of the engagement port, and the child seat 20 is securely held by the anchor 30.



In addition, since the trim cover terminal is not bitten into the engagement port 24a of the engagement member, the trim cover terminal is prevented from being damaged by the engagement member, and the appearance quality of the trim cover is not impaired.
アンカ３０がブラケット３２を介在して連結パイプ１６に固定されているため、パッドの凹部１４－１’、トリムカバーの開口１４－２’が前後方向に長くなる。しかしながら、トリムカバーの開口後方のトリムカバーの端末１４－２ｂをパッド凹部１４－１’に引き込んで下方に逃がしているため、凹部１４－１’、開口１４－２’が前後方向に長くなっても係合部材が開口後方のトリムカバー端末１４－２ｂを噛むことはなく、トリムカバー端末の噛み込みを防止できる。　 Since the anchor 30 is fixed to the connecting pipe 16 via the bracket 32, the pad recess 14-1 'and the trim cover opening 14-2' are elongated in the front-rear direction. However, since the terminal 14-2b of the trim cover behind the opening of the trim cover is drawn into the pad recess 14-1 ′ and released downward, the recess 14-1 ′ and the opening 14-2 ′ become longer in the front-rear direction. However, the engaging member does not bite the trim cover terminal 14-2b at the rear of the opening, and the biting of the trim cover terminal can be prevented. *
ブラケット３２に連結部材４０の端を係止することによって、開口後方のトリムカバーの端末１４－２ｂの噛み込みの上から有利といえないブラケットを有効に利用できる。



　また、連結部材４０が、連結パイプ１６に巻装されているため、開口後方のトリムカバー端末１４－２ｂ、ブラケット３２間に連結部材を容易に張設でき、適切な牽引力のもとでトリムカバーの端末１４－２ｂをパッドの凹部１４－１’に引き込むことができる。　 By locking the end of the connecting member 40 to the bracket 32, it is possible to effectively use a bracket that is not advantageous from the top of the trim cover terminal 14-2b at the rear of the opening.



Further, since the connecting member 40 is wound around the connecting pipe 16, the connecting member can be easily stretched between the trim cover terminal 14-2b at the rear of the opening and the bracket 32, and the trim cover can be applied under an appropriate traction force. The terminal 14-2b can be drawn into the pad recess 14-1 '.
後突、急停車などにより大きな荷重がチャイルドシート２０に作用すると、その荷重がチャイルドシートの係合部材２４を介してアンカのフロントバー３０ｂに伝達され、アンカ３０は曲げ剛性のもとでその荷重を受ける。そして、アンカのサイドバー３０ａの後端が連結パイプ１６に固定され、フロントバー３０ｂがサイドバー前端に連結された片持ち形状にアンカ３０は成形されているため、アンカに大きな荷重が作用して、曲げ剛性で荷重を支え切れないと、アンカの変形、具体的には、サイドバーの変形が避けられない。


When a large load acts on the child seat 20 due to a rear collision, sudden stop, etc., the load is transmitted to the anchor front bar 30b via the child seat engaging member 24, and the anchor 30 receives the load under bending rigidity. And since the anchor 30 is formed in a cantilever shape in which the rear end of the side bar 30a of the anchor is fixed to the connecting pipe 16 and the front bar 30b is connected to the front end of the side bar, a large load acts on the anchor. If the load cannot be supported by the bending rigidity, the deformation of the anchor, specifically, the deformation of the side bar cannot be avoided.


しかしながら、アンカのサイドバー３０ａは直立位置から斜め前方に延出して設けられているため（図３（Ａ）参照）、サイドバーは、曲げ変形ではなく座屈変形するが(図３（Ｂ）参照)、座屈変形は曲げ変形に比較してその変形量は小さい。



　さらに、フロントバー３０ｂに係合されたチャイルドシートの係合部材２４はサイドバー３０ａの変形に伴って下降するが、ブラケット３２は係合部材の下方で当接可能な位置にあるため、下降する係合部材の下面２４’がフロント壁の上端３２ｂ’に当接して、ブラケットが荷重を受けて係合部材の下降、つまりは、サイドバーの変形を阻止する。　 However, since the anchor side bar 30a extends obliquely forward from the upright position (see FIG. 3A), the side bar is buckled but not bent (FIG. 3B). The buckling deformation has a smaller deformation amount than the bending deformation.



Further, the child seat engaging member 24 engaged with the front bar 30b is lowered with the deformation of the side bar 30a, but the bracket 32 is in a position where it can be contacted below the engaging member. The lower surface 24 'of the combined member abuts against the upper end 32b' of the front wall, and the bracket receives a load to prevent the engaging member from descending, that is, the side bar from being deformed.
そのため、後突、急停車などによって大きな荷重がチャイルドシート２０に作用して係合部材を介してアンカ３０に伝達されても、アンカの過度の変形が、アンカを大径化することなく、確実に防止できる。　 Therefore, even if a large load acts on the child seat 20 and is transmitted to the anchor 30 via the engaging member due to a rear collision, sudden stop, etc., excessive deformation of the anchor is reliably prevented without increasing the diameter of the anchor. it can. *
また、連結パイプ１６の前周面を抱持する切欠き３２ｃをブラケットのサイド壁３２ａの後端に設けているため、十分な固定長さ（溶接長さ）が確保される。そのため、ブラケット３２は連結パイプ１６に強固に固定され、チャイルドシート２０からアンカ３０に伝達された荷重に十分に耐えられる。



　さらに、ブラケットのフロント壁３２ｂは、係合部材２４の延出方向(前後方向)と直交する方向(左右方向)に位置するため、チャイルドシート２０が左右方向にずれてシート１０に載せられても、係合部材の下面２４’がフロント壁上端３２ｂ’に確実に当接される。　 Moreover, since the notch 32c which holds the front peripheral surface of the connection pipe 16 is provided at the rear end of the side wall 32a of the bracket, a sufficient fixing length (welding length) is ensured. Therefore, the bracket 32 is firmly fixed to the connection pipe 16 and can sufficiently withstand the load transmitted from the child seat 20 to the anchor 30.



Furthermore, since the front wall 32b of the bracket is located in a direction (left-right direction) orthogonal to the extending direction (front-rear direction) of the engaging member 24, even if the child seat 20 is shifted in the left-right direction and placed on the seat 10, The lower surface 24 'of the engaging member is securely brought into contact with the front wall upper end 32b'.
上記のように、連結部材の張設によってトリムカバーの端末をパッドの凹部に引き込んで開口後方のトリムカバーの端末を下方に逃がしているため、チャイルドシート背面の係合部材が開口後方のトリムカバー端末を噛むことがなく、係合部材先端の係合口へのトリムカバー端末の噛み込みが防止される。そのため、アンカのフロントバーが係合口の末端まで入り込んで係合され、チャイルドシートがアンカに確実に保持される。　 As described above, since the end of the trim cover is pulled into the recess of the pad by extending the connecting member and the end of the trim cover behind the opening is released downward, the engagement member on the back of the child seat is the trim cover terminal behind the opening. The trim cover terminal is prevented from biting into the engagement port at the tip of the engagement member. Therefore, the front bar of the anchor enters and engages to the end of the engagement port, and the child seat is securely held by the anchor. *
上述した実施例は、この発明を説明するためのものであり、この発明を何等限定するものでなく、この発明の技術範囲内で変形、改造等の施されたものも全てこの発明に包含されることはいうまでもない。　 The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations, etc. within the technical scope of the present invention are included in the present invention. Needless to say. *
たとえば、実施例では、アンカはシートクッション側に設けられている。すなわち、シートクッションフレームの左右一対のサイドフレームの後端間に架設された連結パイプにブラケットを介してアンカが固定されている。しかしながら、アンカをシートバック側に設けてもよく、シートバックフレームの左右一対のサイドフレームの下端間で左右方向に架設された連結パイプにブラケットを介して固定してもよい。



　また、チャイルドシートとしてＩＳＯ－ＦＩＸタイプのものが通常使用されるが、これに限定されず、ＩＳＯ-ＦＩＸタイプ以外のチャイルドシートにも本発明が応用できる。 For example, in the embodiment, the anchor is provided on the seat cushion side. That is, the anchor is fixed to the connecting pipe laid between the rear ends of the pair of left and right side frames of the seat cushion frame via the bracket. However, the anchor may be provided on the seat back side, or may be fixed to a connecting pipe that is installed in the left-right direction between the lower ends of the pair of left and right side frames of the seat back frame via a bracket.



In addition, an ISO-FIX type child seat is usually used, but the present invention is not limited to this, and the present invention can be applied to child seats other than the ISO-FIX type.
本発明は、チャイルドシートの保持に使用されるアンカを有した車両用シートに広範囲に利用できる。 The present invention can be widely used for a vehicle seat having an anchor used for holding a child seat.
